AIR-COOLER AND REFRIGERATOR.

SPECIFICATION forming part of Letters .E'atent No. 643,763, dated March 6, 1900.

Application am June 2i, 189 Serial No. 721,354. (No model.)

To all whom it new]; concern:

Be it known that I, JOHN CORMAOK, a subject of Her Majesty the Queen of Great Britain, residing at St. Johns, Newfoundland, have invented certain new and useful Improvements in Air Ooolers and Refrigerators atmosphere of a room.

A further object is to provide a construction which can be readily cleansed, which is neat and attractive in appearance, durable in construction, and which can be made at a moderate cost.

To these and other ends, the nature of which will be set forth in greater detail as the invention is described, myinvention consists in the improved construction and combination of parts hereinafter f'u'lly described, and particularly poin ted out in the appended claim.

In the accompanying drawings, in which similar numerals of reference indicate similar parts in all the views Figure 1 is a perspective view showing my improved device, the lid being shown as raised and the refrigcrator-door shown as open. Fig. 2 isfa plan view, the lid and the supplemental top'being removed in order that a better showing of the interior may be made. Fig. 3 is a vertical longitudinal sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a vertical cross-sectional view taken on the line 14 of Fig. 2.

1 designates my improved cooler, comprising the bottom 2, the top 3, hingedly connected to one of the sides 1, and the ends 5, forming a complete inclosing casing.

, Within the chamber formed by the casing is located a receptacle 6,having an open top, the upper end of the walls of said receptacle being bent outwardly, as at 7, for an object to be hereinafter set forth. As shown in the drawings, the space formed between the walls of the receptacle 6 and the casing is to with the bottom of the receptacle 6 and also serves to allow of the formation of a passageway between the bottom of the receptacle 6 and the bottom 9, as best shown in Figs. 3 and 1. The end 11 is carried upward above the top 10, said upwardly-extending portions, to"- gether with the extensions formed on the'sidle, as best shown in Figs. 3 and 4, serving to form a supplemental chamber which is adapted to v be filled with non-conducting material simi lar to that'used in the space between the walls of the receptacle 6 and the casing, the up Wardly extending portions being bent in= wardly, these inwardlyextending portions and the flange 7 serving to prevent the accidental forcing of the non-conducting material out of its proper place over the edges of said receptacle 6 and the walls of the chamber 7 a into the space formed between the walls of the receptacle 6 and the walls of the chamber 7. Above the top of the receptacle 6 and the chamber 7, directly below the top 3, is interposed a removable supplemental top 12, which serves toclose the upper portion of the device. tween the walls of the receptacle 6 and the walls of the chamber 7 is not inclosed at its top, the closing being accomplished by means of the top 12. As this space is adapted to receive the refrigerating material, it is often times necessary that access be had'thereto without removing the top 12, and-to accomplish this I provide hinged doors 13, (shown in Figs. 1 and 3,) which doors are located directly above the space.

As shown in Figs. 1 and 3, one end of the refrigerator is provided with an opening As best seen in Fig. 2, the space be- ICO Within the chamber 7 suitable shelves are provided, on which it is possible to place any articles which are to be kept cool.

16 designates a shaft which extends through the casing, the receptacles 6, and the walls of the chamber 7, having its inner end provided with a suitable fan 17, the outer end of said shaft being provided with suitable power-applying means, such as a pulley, which is connected to a suitable motor or, if desired, a spring-motor connected thereto, the object being to cause the fan within the refrigerating-chamber to be rapidly rotated, which serves to keep the cool air within thechamber constantly circulating and at the same time causing this cool air to be forced outward through a suitable pipe 18 to the point where it is desired to use this air. As shown in the drawings, the space between the walls of the receptacle 6 and the walls of the refrigerating-chamber is provided with a plurality of openings, in which are secured suitable cocks 19, which serve to allow of the withdrawal of the water which may be formed within the space and also to allow of the ready cleansing of these parts.

In operating my improved cooler the space between the Walls of the receptacle 6 and the walls of the chamber 7 a is first packed with ice and the cooler closed. As the refrigerating material is located on all sides of the chamber 7 with the exception of the top, where insulating material is placed, it will be readily seen that the air within the chamber .7 will be quickly cooled. As the fan 17 is rotated, the air within the chamber 7 is kept in constant circulation and is forced outward through the pipe 18 to the sleeping-room or sitting-room or other suitable points, as may be desired.

The advantages of this construction are many and are believed to have been fully pointed out and are of so obvious a nature as to render their further description unnecessar Vl hile I have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.

A cooler andrefrigerator, comprising a casing, a hinged top therefor; a receptacle mounted within said casing, said receptacle having an open top; non-conducting material inter posed between the walls of said receptacle and said casing; a closed refrigerating-chamber' located within said receptacle, said chamber being of a less size than said receptacle, whereby a space will be formed between the walls of said chamber and the walls of said receptacle, said space abutting against the sides, end and bottom walls of said chamber and forming a repository for the refrigerating material; a supplemental top removably interposed between said hinged lid or top and said receptacle, said top being provided with a series of openings leading to said space, said openings being normally closed by hinged doors, a space being formed between the top of said chamber and said supplemental top; non-conducting material located within said space above said chamber; and a door adapted to afford access solely to said refrigeratingchamber, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

JOHN CORMAOK.
